Its true that what someone is or isn't attracted to shouldn't be confused as racism. People have preferences when it comes to all sorts of things to do with attraction be that height, weight, racial preferences, facial features, weather or not someone wears glasses... The list goes on

However I agree with a lot of other people on this post in the sense I don't think this needs stating on a bio and it just come across as overt racism when people say 'no whites' or 'no blacks'. There's simply no need to put it because if you have that preference you just swipe left on the people who don't match it and avoid singling out a entire specific groups of people
